The story begins with the Emperor of Mifan, Chiaotzu, seeking the Dragon Balls to extend his reign over the kingdom. In his quest for power, Chiaotzu captures Goku’s best friend, Krillin, who possesses one of the Dragon Balls. Upon learning of Krillin’s capture, Goku, accompanied by his lifelong friend Bulma, sets out to rescue him and recover the Dragon Ball.
As Goku and Bulma travel to Mifan, they encounter a group of mercenaries led by General Tao, a fearsome warrior who has a personal grudge against Goku. A fierce battle ensues, but Goku manages to defeat Tao and his henchmen, freeing Krillin in the process.
Meanwhile, the reigning king of Mifan, King Chappa, discovers Chiaotzu’s true intentions and attempts to stop him. However, Chiaotzu uses his telekinetic powers to incapacitate King Chappa and take control of the kingdom. Determined to restore peace, Goku and his friends join forces with King Chappa and his daughter, Princess Misa, to overthrow Chiaotzu’s tyrannical rule.
To confront Chiaotzu and reclaim the kingdom, Goku and his allies participate in the World Martial Arts Tournament hosted by Mifan. Along the way, they encounter formidable opponents, including the shapeshifting pig Oolong, the shape-memory sorcerer Puar, and Yamcha, a skilled desert bandit turned martial artist. These encounters lead to exhilarating battles filled with intense martial arts action.
As the tournament progresses, Goku faces off against the powerful mercenary, Master Shen, who is Chiaotzu’s master and a former rival of Goku’s late martial arts teacher, Master Roshi. Goku’s determination and strength enable him to defeat Master Shen, proving his growth as a warrior.
In the climactic final showdown, Goku confronts Chiaotzu and his loyal bodyguard, Tien Shinhan, who possesses incredible strength and an arsenal of powerful techniques. The battle pushes Goku to his limits, but through sheer perseverance and his signature move, the Kamehameha, he defeats Tien and ultimately convinces him to turn against Chiaotzu.
With Chiaotzu defeated and Tien joining Goku and his friends, they rally together to overthrow Chiaotzu’s rule and restore King Chappa to his rightful place as the ruler of Mifan. The movie concludes with Goku bidding farewell to his newfound allies as he sets off on his next adventure, promising to return stronger than ever.
